A compressor and a method of manufacturing the same are disclosed. The compressor includes a piston having formed therein a suction space, in which refrigerant gas is sucked; and a cylinder in which a piston is accommodated, the cylinder defining a compression space that is configured, based on the piston reciprocating in an axial direction, to compress the refrigerant gas therein. A plurality of grooves having a partial spherical shape and having a diameter of 10 micrometers is formed in an outer circumferential surface of the piston or an inner circumferential surface of the cylinder.
